Since each astrological sign has characteristics which are similar to those of a planet, it is said to be in analogy with the planet involved. All signs are ruled by, or under the rulership of a planet.
Besides, a sign may be fairly compatible with another planet even if the planet is not its ruler, and conversely, a planet may symbolise values unconnected to those of the sign it tenants, and in such cases, the planet\'s expression becomes rather negative or less significant.
Depending on its state, a planet is referred to as dignified or debilitated. Five states are possible: rulership, when the planet is in the sign(s) it rules, detriment, exaltation and fall. The fifth state is referred to as peregrine: a planet is peregrine when it is in none of the four states enumerated above. Lastly, it is important to mention that modern astrologers do not agree on the importance of planetary dignities and debilities. Therefore, caution is to be exercised. On Astrotheme, we take them into account, but with moderation, in our astrological reports and our on-line applications.
